Understanding How Wireless Alarm Systems Work

How It Works1 Low Res

When it comes to increasing home security and offering more flexible solutions, wireless technology is one of the most important developments of the last decade. It allows monitoring from afar, and it can easily be integrated with wired and broadband-based system to provide better, more complete coverage.
In order to buy the best wireless system and get the most from it, though, you need to know just how wireless works. The principles are fairly basic, but the permutations of how it can work can be quite complex.

Wireless home protection works when signals are sent from sensors placed around the home after an intruder sets them off. These signals then go to a central control panel, which in turn alerts either a call center or local law enforcement that someone unauthorized has entered the home. In the early days of wireless home protection, false alarms were quite common, but now these are relatively rare.

The control panel acts as a kind of central hub of the system. It is commonly placed in an out of the way location within the home so that burglars can’t smash it to disable the entire system.

The other components of the system are the keypads, which allow authorized entry once a pass code is entered. Keypads are normally positioned at the entryways to the home.

In addition to alerting the call center or local enforcement, some control panels will generate an audible alarm when a violation occurs. Sometimes the dispatcher at the call center will attempt to verify the validity of the intrusion; other times, the call center simply calls the local police. Some wireless systems are more sophisticated, with the ability to detect flooding, fire and other problems.

Those same sophisticated systems can receive a page or text to deactivate the alarm, which is particularly useful for families who have kids coming home from school. The more advanced systems use cellular communication, which is considered more reliable. And high-end systems are normally designed to be wireless from beginning to end, while others rely to some degree on a wired signal as the foundation or a critical link in the system.
